Title: Manufacture of polysilicon resistor
Inventor: SHIMOTORI YUTAKA
IPC: H01L21/822
Filed: 1990-02-27
Abstract: PURPOSE:To omit a thermal treatment process for removing hydrogen, and to relax the conditions of heat treatment by forming an amorphous silicon film by using a gas, into which silane and borane are introduced simultaneously, executing laser annealing to the surface of the amorphous silicon film and forming a polysilicon film as a resistance layer. CONSTITUTION:When an amorphous silicon film 14 is shaped through a plasma CVD method, silane (SiH4) and borane such as diborane (B2H6) are introduced simultaneously into the furnace 13 of a device. Consequently, the amorphous silicon film 14, to which borane as impurities is added, is formed, borane is bonded effectively with the silicon (Si), and the content of hydrogen (H) is reduced with the bonding. Accordingly, roughening by hydrogen (H) of the surface of a polysilicon film 16 is inhibited even through laser annealing is carried out without executing the heat treatment of hydrogen removal as seen in conventional devices. When heat treatment is executed for further removing hydrogen positively, a temperature can be lowered and the treating time is shortened.

Filed: 1979-04-20
Abstract: PURPOSE:To form a fine pattern by providing a reflected-elecron absorbing layer of resin and the like which are not sensitive to an electron beam on a substrate, and applying electron-beam sensitive resist thereon. CONSTITUTION:Polyimide-series resin 1 which is not sensitive to an electron beam  is applied on all the surface of a substrate 3. The thickness is determined so that the reflected electrons from the substrate 3 do not affect electron-sensitive resist. The thickness is usually 0.05-1mum. After the burning, negative electron-beam sensitive resist 2 is applied until the thickness of about 0.1-1mum is obtained. Then, after the burning, an electron beam 5 is emitted according to a desired pattern 4, and development is performed. A fine pattern is obtained by removing the exposed resin 1. It should be noted that the electron-sensitive resist 2 is not etched when the resin is removed. In this method, the effect of the reflected electrons from the substrate on the electron-beam sensitive resist can be removed, expansion of the lower edge of the electron-beam sensitive resist and the remnants of whiskers can be eliminated, and the fine pattern can be accurately formed. An ultraviolet ray may be used by selecting a resist.

Abstract: PURPOSE: To achieve smaller compression mechanism and higher utilization efficiency of compressors by making combination use of the low and high stage compressors disposed in series and an intermediate vessel for pressure medium gas and performing the sequential control operations suitably coupling these at the time of subjecting the object to be treated in a high-pressure vessel to hot hydrostatic pressing.  
     CONSTITUTION: The pressure medium gas having an intermediate pressure in an intermediate vessel 5 is fed into a high-pressure vessel 1 owing to a differential pressure, whereby initial filling is done. Next, when the respective internal pressures of the both vessels balance approximately, the gas in the vessel 5 is fed and filled in the vessel 1 through a high-stage compressor 4. Thence, at the stage when the internal pressure of the vessel 5 lowers down to a desired pressure, the pressure medium gas in a gas gathering device 2 is fed into the vessel 1 through the high- stage compressors 3, 4. When the internal pressure of the vessel 1 reaches a desired pressure, the accepting is stopped and the inside of the vessel 1 is maintained at high temperature and high pressure, whereby the object to be treated is subjected to hot hydrostatic pressing. During this time, the gas of the device 2 is fed to the intermediate vessel 5 via the compressors 3, 4. Further when the treatment of the object to be treated in the vessel 1 is completed, the gas in the vessel 1 is recovered into the vessel 5 or the device 2.
